Does the 85 gt 2.8 have a fan in the trunk for the cooling tube's, an if so does the fan go on when the key is turned on or when the motor is. I have never heard it run.
That tell's me why iv never heard it. My rad switch was bad when i got my car with some other things. Fixed most but still need to change coolent sending an rad fan switch. Thank's for the info...
Or you can just take the fan out and throw it away. Its debatable, but I think theyre useless. I threw them away on all my cars. If I remember 88s didnt have one to start with. I never saw any ill effects.

There's plenty of time to throw it away after it burns out. I think the 88's also had a better alternator which may be able to handle heat better.

Yes, the 88's have an alternator that better cools itself, and there's also superior heat shielding in place near the ignition coil. Roger tends to overlook these facts.
Well I do have one an it does work, so I will use it till it stop's working it can't hurt an only help keep thing's cooler witch is always a good thing in the summer. Thank's again to all for the feed back!! Next on the list , new brake pad's an flush job.

They are good little blower motors. I've had mine running full time for a year and it's still going. If your cooling system is working correctly, the fan doesn't come on that much. The alternator and coil see a bunch of heat between fan cycles. Something to think about.
My 87 has the cooling fan, my 88 does not. I'm still running the original 87 alternator while the 88 has gone through three alternators. The fan must do something.
Boostdreamer, how did you wire it up to come on when the motor is on? Can you tell me a easy an good way to do it.
Here is a write-up I did. Hope it helps!
TRUNK BLOWER:
Have you ever noticed the two bent tubes that are attached to the trunk wall that faces the engine? Do you know what they are? They are there to direct air to the coil and the alternator.
Do you know were the forced air comes from? Inside your trunk! On the passenger-side of the trunk there is a blower mounted between the carpet and the fender. Pull the carpet away from the rubber trunk weatherstrip to locate it.
This blower works in conjunction with the radiator fan. They come on at the same time. Even though these cars are 20 years old, these blowers have seen very little run time. Our little engines are designed to run at relatively high temperatures but the electrical componets are not. Heat is deadly to them. I have re-wired this blower to work at all times when the key is in the run position. It is easy. Here's how you do it:
There is a relay beside the blower that is held on by two 7mm bolts, remove them to give yourself better access to the wiring. You will see five wires going into the relay. Three brown, a green/white, and one black/red wire. Peel the tape back and you will see two of the brown wires are actually the same wire used as a jumper.
Cut the brown wire that is not a jumper about 4-5 inches from the relay. Cut the black/red wire an equal distance from the relay. Strip some insulation from the four ends of wire. Use a wire nut to connect all four wire ends.
Re-tape the bundle of wire and replace the two 7mm bolts. Now whenever the key is in the RUN position, that blower will be working.
Thank's for the how to boostdreamer for hooking up the fan. Ill do it today or tomorrow, Also clean the fan. The fan work's but I will make sure there is no crap in it. It look's new out of the box!

I put lots of miles on all my cars. No fans worked fine in all mine for over 100K miles. Only alternator or coils I ever put in any of them was when I did the original rebuilds. I just do what works and always remove useless clutter I also throw out all the nasty fiber insulation on the firewall that dont do anything but trap dirt and water.. Those fans dont put out any air anyway. They wouldnt blow up a balloon. They might make a piece of paper flutter. Theres people in here that use aluminum tire valve stems to save weight, but they want to keep a 2 pnd dead weight fan.
I put my hand in front of my coil blower today. It blows very nicely. Since the blown air is split in two, the blower must be a decent little unit. I would have checked the alternator tube output but my manifold was hot.
